Steve Jobs, who died at 56 on Wednesday (October 5), was not just the visionary behind Apple and its groundbreaking technology, but also a leading force at Pixar, the Oscar-winning animation studio responsible for films like "Toy Story," "Finding Nemo," "Up" and more. His contributions to movies, both in terms of story and the way these stories are discovered by viewers, are immeasurable.

Actors and filmmakers from Alec Baldwin to Kevin Smith have reacted to Jobs' death on Twitter. Read their memories, quotes and more after the jump.

@joshgad Thank you Mr. Jobs. You were Disney, Edison, and Houdini all rolled into one. And you will be greatly missed. RIP

-Josh Gad, Actor ("The Book of Mormon")

@AlecBaldwin Sad about Steve Jobs. On par with Henry Ford, Carnegie and Edison.
